LAMP.

SPECIFICATION forming part of Letters Patent No. 446,400, dated February10, 1891.

Application filed May 5, 1890. Serial No. 350,639. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM A. WRIGHT, a citizen of the United States,residing at Centreton, in the county of Burlington, State of New Jersey,have invented a new and useful Improvement in Lamps, which improvementis fully set forth in the following specification and accompanyingdrawings.

My invention relates to improvements in lamps or burners for lightingand heating purposes; and it consists, first, of a lamp provided with afiltering-stone for the burningfluid or oil, and, second, of thecombination of parts herein set forth.

Figure 1 represents a vertical section of a lamp embodying my invention.Fig. 2 represents a plan View of the perforated head or cap employed onthe lamp. Fig. 3 represents a plan view and partial sectional View ofthe stone shown in Fig. 1.

Similar letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings, A designates a lamp or heater having in itsbody portion an oil-chamber B which is supplied by means of aninlet-pipe 0, adapted to connect with a reservoir or other suitablesource of supply. The said chamber is preferably constructed with aninner partition-wall D, so that the oil passes first within a tubularpipe formed thereby before it enters the chamber. The upper end of thesaid chamber B is closed except at the openings F, formed in the plateG, covering the said chamber. A central airtube lI passes through thechamber B, entering at the lower end thereof, and connected atits lowerend with a compressed-air supply and at its upper end communicating withthe upper portion of a chamber J, located above the said chamber B.Fitting in the chamber J is a filtering block or stone K of fineporosity, similarin character to an emery-stone. The said stone has acentral vertical opening L therein and radial passages M, as shown inFigs. 1 and P designates a head or cap having an interior screw-threadon itslower end, so as to be adapted to closely fit on the body of thelamp and thereby keep the stone K in place, and provided with an outerrimmed flange R to support a flue or globe S, and an inner projectingflange 'l with a circular row of openings U, through which the oilpasses for the purpose of combustion.

On the upper end of the cap P is tightly fitted the slotted cap Q. Theblock K may be either of natural or artificial stone or of wood, theessential feature being its fine porosity, so that the oil may passthrough the same.

Oil or other burning-fl uid, which is supplied to the chamber 13 by thepipe O, enters the chamber J by the openings F in the plate G, andpassing through the filtering-stone K is ignited on the upper surface ofthe flange 'l at the openings Uthereof by means of a wick V, which isinserted in the central opening L thereof, having its lower endprojecting below said stone and into the oil in the chamber J. Theradial passages M communicate with the central opening L, so that thewick is reliably fed or supplied with the oil. The current of air whichenters the tube H is under a uniform pressure, so as to secure a steadyflame with intense heat, whereby the device may be used, if desired, forgenerating heat for motors, &'c., as well as for lighting purposes.

Instead of using air in combination with the oil, the tube H may beconnected with a gas-supply, so that mingled gas and oil may be used,thereby producing a brilliant flame.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A lamp having a central air-tube and a surrounding oil-chamber, acovering-plate for said chamber having openings therein, an upperchamber with filtering-bl0ck, and a head with openings therein securedto the upper end of the body of the lamp, said parts being combinedsubstantially as described.

2. A lamp having a central air-tube and a surrounding oil-chamber withan inner partition, a covering-plate for said chamber having openingstherein, an upper chamber with filtering-stone, a head with an innerflange having openings therein and an outer rimmed flange, and a slottedcap, said parts being combined substantially as described.

3. Alamp having an upper and alower oil chamber, an air-tube leadingintosaid upper chamber, a head with openings therein, a filtering-block, anda slot-ted cap on said head, said parts being combined substantially asdescribed.

4:. In a lamp, a filtering-stone with a vertical opening" therein, incombination with a head having openings therein, and an oilchamber,substantially as described.

5. A lamp havingafiltering-stone provided with a Vertical opening, andradial passages communicating With said Vertical opening, in combinationwith an oil-chamber, substantially as and for the purpose set forth.

0, A lamp having an oil-chamber with an inner partition, a centralair-tube, a covering plate for said oil-chamber provided with opening's,an upper oil-chamber communicating with the first-mentioned oil-chamber,a head with openings therein, a filteringstone in said upper chamber andhaving, a vertical opening therein, said head having an inner flangewith openings therein, and a slotted cap, said parts being combinedsubstantially as described.
